Showtime bet on boxing pays off

In two years at the helm of Showtime Sports, Stephen Espinoza has the network's boxing franchise at an all-time high and poised for another big year in 2014.

Showtime got involved in boxing in 1986. While it has been home to a number of major fights, producing several significant pay-per-views featuring Mike Tyson and Julio Cesar Chavez Sr. in the 1990s, the network has always been a second-class citizen to premium cable leader and rival HBO.
